An energy generation system utilizes convection flow of a fluid media caused by differences in temperature to generate useful energy therefrom. A conduit for directing convection circulation permits conversion of forces associated with the movement of the fluid media in the conduit into a usable energy by its effect of a generation device as the fluid media flows past such device.
